Abstract

Development of irrigation networks is a crucial element in increasing the efficiency and effectiveness of water distribution for agriculture. This research aims to determine priorities for developing irrigation networks in the Bedadung Irrigation Area, Jember Regency, using the Multiple Attribute Decision Making (MADM) method. This method consider various criteria influencing decision-making, such as physical condition of the channel, land area, water requirements, and level of infrastructure damage. This research involved collecting primary and secondary data through field surveys, interviews with interpreters, as well as reviewing technical and administrative documents related to irrigation networks. Data was analyzed using several MADM techniques, such as Simple Additive Weighting (SAW), Weighted Product (WP), and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to obtain the weight of each criterion and determine development priorities. The results show that the main priority for developing irrigation networks in the Bedadung Irrigation Area is repairing primary, secondary, and tertiary canals that are badly damaged, followed by increasing canal capacity to meet water needs in the dry season. Implementation of the results of this research is expected to increase the efficiency of irrigation water distribution, reduce water losses, and increase agricultural productivity.

Abstract

Growing rice is complicated because of the interrelationship among production components, one of which is soil conditions. Determination of soil conditions is usually conducted by employing some soil properties. It is no doubt that soil properties have spatial and temporal characteristics. This research used two soil properties: Electrical conductivity (EC) and pH. This study aimed to use and evaluate Inverse Distance Weighted to uncover the temporal changes in pH and EC during the rice growth period. The methods used in the research were field survey, soil sampling, laboratory analysis, and data processing in Geographical Information Systems (GIS). The sample used was 30 and repeated three times under the growth period (vegetative, generative, and ripening). The results showed that there were changes in pH values of the soil in one growing season, and EC values tend to increase from the vegetative to the ripening period.

Abstract

Universal Soil Loss Equation (USLE) and Geographical Information Systems are two spatial soil erosion analysis models because both have a spatial context. As an important factor, soil erodibility is crucial in determining soil erosion, with C-organic significantly influencing the K value. The main aim of this study is to characterize soil erodibility and soil loss based on spatial simulation of the effects of soil C-organic in a GIS environment. Research findings indicated that by simulating within a GIS environment, C-organic can affect soil erodibility and erosion. Low C-organic levels can increase soil erodibility, while high C-organic levels can decrease it. A reduction in C-organic by 10%, 20%, and 30% will increase K by 1.10%, 1.17%, and 1.21%, respectively. Conversely, adding 10%, 20%, and 30% C-organic will decrease K by 1.12%, 1.27%, and 1.46%, respectively. A 10%, 20%, and 30% increase in C-organic can reduce soil loss by 1.2%, 1.3%, and 1.5%, while a reduction in C-organic will increase soil loss by 1.1%, 1.2%, and 1.3%, respectively. A low K value indicates slight erosion, while a high K value suggests high erosion. Continuous C-organic and properly managing vegetation are necessary to maintain and improve soil quality.

Abstract

Rice is one of the agricultural commodities that serves as the foundation of food security. Rice production fluctuates from year to year. Rice production in Jember Regency is mostly produced from irrigated rice fields. Bedadung irrigation area is one of the irrigation areas that has a large service area. UPT Balung is one of the UPTs that often experience water shortages. efforts that can be made to meet agricultural water needs are by optimizing water allocation management in agricultural land. Methods that can be used for water allocation management are the FPR-LPR and evapotranspiration methods. The purpose of this study is to determine the allocation of water, cropping patterns and the best method between the FPR-LPR and evapotranspiration methods on rice plants in UPT Balung Bedadung irrigation area. The research requires data in the form of secondary data which includes climate element data, soil data, crop data and 2022-2023 RTTG data. Water allocation using the FPR-LPR method shows that in growing season 1 requires water of 81,612 l/sec and in growing season 2 of 22,152 l/sec. Water allocation using the evapotranspiration method shows that in growing season 1 requires water amounting to 13,152 l/sec and in growing season 2 amounting to 15,196 l/sec. The best method between the two methods is the evapotranspiration method because the evapotranspiration method is based on climate data, soil data and crop data.

Abstract

Stevia plant, as an alternative to sugarcane, is a plant that is susceptible to drought. The growth and yield of the stevia plant is highly dependent on the availability of sufficient water and nutrients. To get optimal crop yields is necessary to pay attention to the water needs of the stevia-growing media. The right intensity of watering and using organic fertilizers are efforts that can be done to prevent drought. This study aimed to determine the effect of vermicompost and water application intervals on the growth and yield of stevia plants. A divided plot design was used in this study with 12 treatment combinations with three replications. The basic pattern of completely randomized design (CRD) consists of 2 factors with three replications. The main plot is the interval of giving water (I), namely I1 = 1 day, once, I2 = once every 2 days, I3 = once every 3 days and Subplots, namely the dose of vermicompost, consist of 4 levels, namely V0 = 0 tons/ha, V1 = 5 tons /ha, V2 = 10 tons/ha, V3 = 15 tons/ha. The data were analyzed using analysis of variance. The significant difference between treatments is determined using Duncan's Multiple Distance Test at 5%. The best watering interval is the interval of giving once every three days and vermicompost 5 tons/ha.

Abstract

Jember Regency is one of the national food storage areas. One of the most important resources in cultivating food crops is water which comes from rainfall. The existence of rainfall data is very important in planning and implementing agricultural activities. Limited rainfall data is the main problem for agricultural planning. One solution to this problem is to utilize rainfall data from CHIRPS (Climate Hazards Group Infrared Precipitation Station). The use of CHIRPS data is still biased data, so bias correction is needed to measure the level of accuracy of CHIRPS data for estimating rainfall in an area. Bias correction is carried out using two methods, namely multiple linear regression and power regression. The correction results show that the multiple linear regression method is able to produce monthly rainfall that is close to observations with an RMSE value of 3.9 and a coefficient of determination of 0.99. Temporally, the peak of the rainy season in Jember Regency occurs in December while the dry season is in August. In the rainy season (December-January and February) Jember Regency's rainfall is around 300-500 mm/month and in the dry season (June-July-August) it is in the range of 50-200 mm/month. Spatially, the northern part of Jember, especially Sumberbaru, Bangsalsari and Tanggul subdistricts, is wetter than the Jember Regency area as a whole. The southern part of Jember, especially those close to the coast, has lower rainfall than other regions. In the dry season, rainfall in this region is less than 20 mm/month.

Abstract

Lettuce (Lactuca sativa L.) is a leaf vegetable that has a high level of consumer demand and commercial value and can be cultivated using a combination of hydroponic substrate and drip irrigation methods. This research aims to determine the effect of the time interval for providing nutrients on the growth and harvest results of three lettuce plant varieties. Plants were cultivated on cocopeat and husk charcoal media (ratio 1:3) and arranged using a Randomized Block Design (RAK) consisting of two treatments. The first treatment is the nutritional interval which consists of an interval of 2 hours with a discharge of 17 ml (I1), 3 hours with a discharge of 25 ml (I2), and 4 hours using a discharge of 34 ml (I3). The second treatment is the plant variety which consists of the Grand Rapids variety (V1), the Green Coral variety (V2), and the Red Coral variety (V3). The data is analyzed using analysis of variance and if the results obtained are significantly different then a DMRT test will be carried out. The research results showed that the Green Coral lettuce variety was better than the Grand Rapids and Red Coral varieties. This is shown by the results with the highest and best values for the observation variables of number of leaves, plant fresh weight, and chlorophyll content. The nutritional interval which consists of an interval of 2, 4, and 6 hours gave results that were inversely proportional to the variety treatment, that is, they were not significantly different in all observed variables. Keywords: lettuce plants, plant varieties, nutritional interval, substrate hydroponics
